Overview: You have an AI product idea — or an existing product that needs AI built into its core. You need someone who won't just write code, but make the hard architectural decisions that determine whether your product scales or breaks at 10,000 users. That's what I do. I've shipped 5 AI-native products in the last 2 years, each running in production with real users today. Not prototypes. Not demos. Production systems handling real data, real money, and real compliance requirements. Recent results: → Built an AI conversation intelligence platform that analyzes calls across 19 dimensions in real-time — now processing hundreds of conversations daily for a US-based SaaS company → Delivered an AI medical education platform with 11 LLM-powered endpoints, integrating clinical evidence from randomized controlled trials — used by healthcare professionals for continuing education → Shipped an AI learning platform with 9 specialized AI pipelines — 500+ study hours saved for users within months of launch → Architected an AI-powered industrial support system with vector search and multi-tenant isolation — deployed across operator, technician, and admin roles for a European client What makes me different from other AI developers: Most developers bolt AI onto existing products as a feature. I architect systems where AI is a core capability — from database schema to user experience. Every project I deliver includes production infrastructure (CI/CD, monitoring, error tracking), not just application code. I also run a team at Growth Loops Technology, which means I can scale up when your project needs it — without you managing multiple freelancers. I'm the right fit if you need: → An AI-native product built end-to-end (backend, AI pipelines, deployment) → LLM integration done properly (structured output, RAG, multi-stage pipelines) → A senior architect who can own technical decisions and communicate clearly → Someone who ships on schedule and writes code that holds up in production Technical depth (for the engineers reading this): Backend: NestJS, Node.js, TypeScript, Python, FastAPI, Django AI/ML: GPT-4o, Claude, LangChain, LangSmith, Whisper, AssemblyAI Data: PostgreSQL, Redis, BullMQ, Pinecone, OpenSearch, Meilisearch Infra: Docker, GitHub Actions, AWS, Cloudflare R2, Sentry 15+ years of software engineering. Every project delivered with authentication, async job processing, multi-tier caching, and production monitoring baked in from day one.

Since 2019, I've connected early-stage startups with senior developers and designers who actually fit their culture and tech stack. No recruitment BS, no flaky freelancers, just people I've worked with and trust. I run New Wave Devs, an engineering studio working with startups across the US, UK, Canada, Netherlands, and Norway. We do team augmentation, MVP builds, design work, and team rescue when things go sideways. Our engineers work directly with your team, usually onboarded in under a week, and you talk to the engineer, not a sales layer. The bench runs deep. On the frontend, React, React Native, TypeScript, and Flutter. On the backend, Ruby on Rails, Node, Python, and .NET. Plus AI engineers shipping RAG and agentic workflows in production, along with designers, DevOps, and QA. Mostly SaaS, marketplaces, fintech, and mobile. These aren't junior generalists. Our people have scaled Postgres past a billion rows, shipped Stripe Connect marketplace payments, built HIPAA-compliant health platforms, run native apps at over a million monthly users, and put RAG assistants in front of real customers. So whether you're shipping a first MVP or hitting your first real scaling wall, someone here has already done it. Why people work with us: fast onboarding (1 to 7 days), engineers who match your culture, transparent pricing, and a track record of 100K+ in contracts with long-term clients who keep coming back.

I build AI-powered intelligence systems, automation tools, data pipelines, and cloud-ready software for clients who need reliable technical execution. My background combines Python development, quantitative research, cybersecurity study, cloud infrastructure, and data engineering. I started in financial markets and algorithmic research, where I built backtesting engines, signal systems, dashboards, and market-data pipelines. That gave me a strong foundation in statistical thinking, system design, and high-stakes decision tools. Today, my work is broader: I build systems that collect, process, analyze, and explain information. What I can help with: — Python automation and backend tools — AI-assisted research and analysis systems — Data pipelines, dashboards, and reporting tools — Cloud deployment and infrastructure workflows — OSINT-style research tools and investigation workflows — Cybersecurity learning labs and security-aware tooling — API integrations, scraping, cleaning, and structured data processing — Trading, market, and financial analytics when needed I care about clean architecture, reproducible code, documented assumptions, and systems that are easy to maintain after delivery. I do not just build scripts that work once. I build tools that can be understood, extended, and trusted. My long-term focus is intelligence infrastructure: systems that help people turn fragmented information into clear decisions. If you need a technical builder who can combine AI, data, automation, and practical system design, I can help.

I build AI agents and automation systems that replace manual work — RAG chatbots, AI workflows, and API integrations that ship and run in production. Across 33 jobs and 900+ hours on Upwork I've built a testimonial-automation bot, a RAG chatbot trained on 1,600+ videos, and an AI deal-pipeline for real estate. What I do: • AI agents & RAG chatbots (OpenAI, Claude, LangChain) • Workflow automation (n8n, Make, Zapier) + custom Python • Web scraping & data extraction • API integrations & backend (FastAPI, Django, PostgreSQL) Message me or book a quick call — I'll tell you straight whether I can help and how I'd do it.

You probably need one of these: 1) An AI or automation system that works in production, not just a demo 2) A Web3 product that won't get stuck in audit hell 3) A mobile app or device automation pipeline that scales past 10 users 4) Someone to fix infrastructure that someone else broke That's what I do. I'm a polyglot engineer based in Indonesia with 7+ years shipping production systems across AI, Web3, mobile, and the infrastructure that holds them together. What I work on: - AI & Automation — LLM agents, social media intelligence platforms, sentiment & virality pipelines, multimodal workflows (Claude/GPT/Gemini APIs, vector DBs, custom RAG, evals, cost optimization) - Blockchain — Smart contracts on EVM chains (Ethereum, BSC, Polygon, Arbitrum, Base) and Solana. Solidity, Rust, ethers.js, web3.py. Hackathon winner with open-source contributions to production Layer-1 codebases. - Mobile & Cross-platform — iOS and Android development, plus large-scale mobile device orchestration (anti-detect browsers, residential proxy infrastructure, social automation at scale) - Full-Stack & DevOps — Python, TypeScript, Node.js, React, Next.js, Flask, FastAPI. Docker, Nginx, monitoring (Prometheus/Grafana/Loki), VPS provisioning, CI/CD. I own the infra I build, not just the code. Recent production work: → Real-time social listening platform monitoring TikTok, Instagram, and Twitter — sentiment scoring, virality detection, automated stakeholder reports via WhatsApp and Lark → Self-hosted ALPR (license plate recognition) computer vision pipeline replacing expensive cloud APIs for parking management clients → Trading automation: Pine Script strategies wired to Binance Futures via custom webhook gateway How I work: Clear scoping, milestone-based delivery, async-first communication, no ghosting. For larger engagements I prefer a small paid trial first so we both validate fit before committing. Stack: Python, TypeScript, Solidity, Rust, Pine Script · React, Next.js, Flask, FastAPI · Docker, Linux, Nginx, Cloudflare · OpenAI/Anthropic/Google AI APIs · PostgreSQL, Redis, MongoDB Available 20–30 hrs/week. Open to hourly or fixed-price. Let's talk about what you're building.
